Abstract (en)

[origin: WO2019145622A1] A method for diagnosing light sources (4) for a vehicle, the light sources (4) comprising at least one continuous illumination light source and at least one discontinuous illumination light source, the diagnosing method comprising the steps consisting of: · polarising the continuous illumination light source and the discontinuous illumination light source, · acquiring an output voltage of each polarised light source, · comparing the acquired output voltage with a threshold value so as to verify an operating state of each light source, characterised in that: · the polarisation of the continuous illumination light source is performed immediately before a switching phase of said light source, · the polarisation of the discontinuous illumination light source is performed immediately after a switching phase of said light source.
